| 摘 要： | 采用突变理论将定性与定量结合起来,并与模糊数学的隶属函数相结合,对斜坡稳定评价这样的复杂系统,进行多层次目标分解,然后根据归一公式进行量化递归运算,根据斜坡的不同影响因素计算出斜坡稳定总突变隶属函数值,从而对斜坡稳定状态进行模糊综合分析与评判.

| Abstract: | The Analysing and Evaluating slope stability is often complicated because there are various factors and also because the influence exerted is of very difference in degree.This paper is based on catastrophe theory to discuss and analysis the assessment for slope stability.At first,we divide the complex system of slope stability into some subsystems,then put them to quantitative and recursive operation by using the normalization formula so as to obtain the ultimate catastrophe membership function values of slope stability.Finally,we evaluate slope stability according to them. |
